6 Claims.

This inventionrelates--to---a combination tool and handle.

The chief object of the present invention resides in providing a twosocketed handle, complementary formed shank provided tools, and asingular anchor member identicall bearing up on the handle whenselectively associated with a tool shank depending upon which handlesocket the shank then occupies.

The chief feature of the present invention resides in forming thesockets and the shanks of a frusto-polygonal character whereby the toolsmay be disposed in either socket and non-rotatably retained therein; theanchor member effecting a wedging of the shank in the selected socket.

Other objects and features of the invention will be set forth more fullyhereinafter.

The full nature of the invention will be understood from theaccompanying drawings and the following description and claims.

In the drawings- Fig. 1 is a perspective view of a handle connectorportion, hereinafter termed handle, illustrating the same as havinglongitudinally aligned and transversely disposed intersecting sockets.

Fig. 2 is a central sectional view thereof with a tool disposed in theso-called transverse socket and illustrated in end elevation.

Fig. 3 is a similar view of the handle with a tool disposed in theso-called longitudinal socket, the tool being illustrated in top plan.

In the drawings l indicates an elongated handle portion having therein atapered tubular socket H adapted to receive the tapered end of a woodhandle, not shown. Hole I2 is adapted to take a suitable anchor membersuch as a screw, not shown. The handle 19 includes a head portion !3provided with a frusto-octagonal inwardl tapered socket M, the axis ofwhich coincides with the handle axis so that sockets i4 and II aresubstantially aligned.

The head [3 also includes another frustooctagonal inwardly taperedsocket l5 which extends through the head portion and which has its axisdisposed transverse to and intersecting the longitudinal axis of thehandle. The two last mentioned sockets cross each other or intersect.

In Fig. 2, l6 indicates a tool having a blade portion II, a shankportion l8, and a reenforcing portion IS. The shank is complementary inform to the socket l5, but when seated therein does not projectcompletely through the same for reasons hereinafter assigned.

Coaxial with said shank is the threaded bore ZEWA cap-screw bolt havinghead portion 2|, cap portion 22, and threaded shank 23 is adapted tohave the latter threaded into the shank bore 20; and since cap portion22 bears upon face 24 of said head I3, the screw draws the shank l8 intosocket i5 and wedgingly seats the shank therein. Since the socket isregularly polygonal, the hoe blade may be disposed in other positionsthan that shown, such as a biased position, or in a position wherein theplane of the tool includes the handle axis. In this position the toolserves as an ax or chopping tool.

Reference will now be had to Fig. 3. Herein a second tool includes acultivating blade 25 and a stem 26, longitudinally aligned, if desired,with shank 21. This is complementary to socket l4.

Shank 21 includes a transverse threaded bore 28. When this shank isseated in socket I4, the cap screw bolt aforesaid is disposed in thesmaller end of socket l5, and eccentrically thereof as shown. Thethreaded shank 23 is threaded into bore 28 until cap portion 22 againbears upon face 24 of head l3. As shank 21 is drawn upwardly in thedirection of the face 24 of the head and in the socket M, the tapers aresuch that the shank 21 is wedged home in socket 14.

Thus, the cap screw bolt in either instance has threaded associationwith a tool shank to wedgingly seat same in the selected socket and alsoretains the shank in that socket.

The several tools may be cast steel, forgings, and the like. The handlemay be of similar material. The only machining required is the drillingand tapping of the tool shanks. The economy of production and simplicityof construction will be self evident from the foregoing description.

While the invention has been illustrated and described in great detailin the drawings and foregoing description, the same is to be consideredas illustrative and not restrictive in character.

The several modifications described herein, as well as others which willreadily suggest themselves to persons skilled in this art, all areconsidered to be within the broad scope of the invention, referencebeing had to the appended claims.

The invention claimed is:

1. In combination an elongated handle having at one end a head portionwith a longitudinally disposed inwardly tapering socket opening at thatend and a second similar socket disposed transversely of the firstsocket and intersecting same, a tool having a socket seatable similarlytapering shank, the shank having a threaded bore therein, and a threadedanchoring member having a threaded engagement with the shank in thethreaded bore thereof and disposed in the second mentioned socket andhaving operative bearing upon the head portion adjacent that socket fordrawing the shank into a head socket and wedgingly holding the shank inthe socket.

2. Structure as defined by claim 1 wherein each socket is polygonal incross-sectional character and the tool shank is of complementarycharacter.

3. Structure as defined by claim 1 wherein the said transverse socketextends completely through the head portion.

4. Structure as defined by claim 1 wherein the shank threaded bore of atransverse socket mounted tool is disposed coaxially of the shank.

5. Structure as defined by claim 1 wherein the shank threaded bore of alongitudinal socket mounted tool is disposed transversely of theiongitudinal axis of the shank of said tool.

6. Structure as defined by claim 1 wherein the REFERENCES CITED Thefollowing references are of record in the file of this patent:
